Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

Objective:To evaluate the correlation between vascular hyperintensity of magnetic resonance fluid-attenuated inversion recovery (FLAIR) sequence(FVH) and related parameters of magnetic resonance perfusion weighted imaging (MR-PWI) in patients with middle cerebral artery stenosis cerebral infarction, and to explore the hemodynamic factors related to FVH and the effect of FVH on the short-term clinical prognosis of patients.Methods:A total of 116 patients with middle cerebral artery stenosis cerebral infarction in the Department of Neurology, Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University from January 2020 to December 2022 were collected.According to the diagnostic criteria of FVH, they were divided into FVH (+ ) group (78 cases) and FVH(-) group (38 cases). All patients underwent magnetic resonance(MR) and MR-PWI scans.Demographic and cerebrovascular risk factors were collected, clinical neurological function of patients was assessed by national institate of health stroke scale(NIHSS) upon admission and discharge, and cognitive function of patients was assessed by mini-mental state examination (MMSE). Short-term clinical outcome was assessed using modified Rankin scale(mRS) at the 90th day after discharge.The degree of middle cerebral artery stenosis, positive or negative FVH, FVH score, hypoperfusion volume and MR-PWI related parameters, including peak time (Tmax), mean transit time (MTT), cerebral blood volume (CBV) and cerebral blood flow (CBF), were evaluated in relation to clinical symptoms.SPSS 22.0 statistical software was used for t test, Chi-square test and Pearson correlation analysis. Results:There were significant differences in hypoperfusion volume, Tmax, MTT and CBF between FVH (+ ) group and FVH(-) group( t=1.989, 3.830, 5.223, 3.911, all P<0.05). In terms of short-term clinical outcome, the improvement rate of neurological function ((8.25±6.39)%, (12.22±6.08)%) and MMSE score(25.48±1.59), (26.31±1.26) in FVH (+ ) group were significantly lower than those in FVH(-) group, and the number of patients with progressive stroke during hospitalization in FVH(+ ) group was more than that of FVH(-) group(22(28.21%), 4(10.53%)) (all P<0.05). Pearson correlation analysis showed that FVH score was positively correlated with hypoperfusion volume ( r=0.786, P<0.01) and MTT ( r=0.692, P<0.01), and negatively correlated with CBF ( r=-0.568, P<0.01), but no significant correlation with the degree of arterial stenosis ( r=0.363, P>0.05). Conclusion:FVH is closely related to the Tmax, MTT and CBF values shown in MR-PWI, and the incidence of stroke in progression and short-term adverse prognosis are more likely in FVH(+ ) group, suggesting that FVH can be used as a convenient imaging indicator to reflect the hypoperfusion status of patients with middle cerebral artery stenosis cerebral infarction, and can provide an objective basis for further individualized treatment.

Objective To observe the value of 18F-FDG PET/CT semi-quantitative parameters for predicting spread through air spaces(STAS)of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.Methods Data of 85 patients with clinical stage Ⅰa—Ⅲ a lung adenocarcinoma who underwent preoperative 18F-FDG PET/CT were retrospectively analyzed.The patients were divided into positive group(n=23)or negative group(n=62)according to whether pathology showed STAS or not.Clinical and PET/CT data were compared between groups,and logistic analysis was performed to explore the efficacy of each parameter for predicting STAS.Results Significant differences of gender,carcinoma embryonic antigen,clinical stage,pathological grade,micropapillary growth and proportion were found between groups(all P＜0.05).The maximum,the mean,the peak standard uptake value(SUVmax,SUVmean,SUVpeak),as well as the maximum,the mean and the peak standard uptake value normalized by lean body mass(SULmax,SULmean,SULpeak),also the total lesion glycolysis(TLG)in positive group were all significantly higher than those in negative group(all P＜0.05).Patients'gender,proportion of micropapillary growth,SUVmax and SULmax were all independent risk factors of STAS of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.The area under the curve(AUC)of the above parameters for predicting STAS was 0.666,0.912,0.839 and 0.842,respectively,and of the combination was 0.957.Conclusion 18 F-FDG PET/CT semi-quantitative parameters SUVmax and SULmax were helpful for predicting STAS of clinical stage Ⅰa—Ⅲ a lung adenocarcinoma,and further combination of gender and proportion of micropapillary growth could improve diagnostic efficacy.

With the world aging aggravation,the prevalence of neurodegenerative diseases has risen year by year,which brings a huge burden on society and family.However,the effective treatment drugs are still scarce,there is an urgent need to discover new therapeutic targets and develop new therapeutic strategies.Recent studies have found that the the mitochondrial calcium uniporter(MCU)has an important function in many neurodegenerative diseases,the imbalance of mitochondrial calcium homeostasis caused by its abnormal expression or function is one of the important mechanisms of neurodegenerative diseases.Inhibiting the MCU function can play the good neuroprotective role,the specific inhibitors of MCU have shown the good prospect in treating various neurodegenerative diseases.This paper sketched the structure,function,regulatory mecha-nism and specific inhibitors of MCU,and focused on analyzing the role of MCU in the occurrence and develop-ment of different neurodegenerative diseases in order to provide reference for further exploration of MCU as a new therapeutic target for neurodegenerative diseases.

And the effect of risk factors on the occurrence of ADR was identified by classification weighting. The important risk factors were classified as follows：past history， medication information， name of combined drugs， disease status， number of combined drugs and personal data. ConclusionIn the real world data of rare ADR with a large amount of clinical variables， this paper realized accurate ADR prediction on high-dimensional and class imbalanced condition， and classified and identified the key risk factors and their clinical significance of categories， so as to provide risk early warning for clinical rational drug use and combined drug use， as well as scientific basis for reevaluation of safety of post-marketing TCM.

The liver has a complex cellular composition and a remarkable regenerative capacity. The primary cell types in the liver are two parenchymal cell populations, hepatocytes and cholangiocytes, that perform most of the functions of the liver and that are helped through interactions with non-parenchymal cell types comprising stellate cells, endothelia and various hemopoietic cell populations. The regulation of the cells in the liver is mediated by an insoluble complex of proteins and carbohydrates, the extracellular matrix, working synergistically with soluble paracrine and systemic signals. In recent years, with the rapid development of genetic sequencing technologies, research on the liver's cellular composition and its regulatory mechanisms during various conditions has been extensively explored. Meanwhile breakthroughs in strategies for cell transplantation are enabling a future in which there can be a rescue of patients with end-stage liver diseases, offering potential solutions to the chronic shortage of livers and alternatives to liver transplantation. This review will focus on the cellular mechanisms of liver homeostasis and how to select ideal sources of cells to be transplanted to achieve liver regeneration and repair. Recent advances are summarized for promoting the treatment of end-stage liver diseases by forms of cell transplantation that now include grafting strategies.

Objective:To investigate the feasibility and safety of suprapubic bladder puncture and gland fixation in transurethral enucleation of the prostate.Methods:The clinical data of 15 patients with benign prostatic hyperplasia admitted to the First Affiliated Hospital of Guangxi Medical University from January 2020 to June 2020 were retrospectively analyzed. The age was (70.27±5.35) years old, preoperative serum prostate-specific antigen (PSA) level was (3.03±1.37) ng/ml, preoperative total prostate weight was 80.3(70.49, 96.78)g, preoperative postvoid residual urine volume(PVR)was 80 (55, 108)ml, and the maximum urine flow rate (Q max) was (6.13±2.25) ml/s. The international prostate symptom score(IPSS) was 25(22, 27), quality of life (QOL)score was 5(5, 6), international erectile function index-5 (IIEF-5) score was (15.38±5.10). All 15 patients underwent conventional transurethral plasma enucleation of prostate by using the three-lobe method, and the enucleated gland was pushed into the bladder completely. Then a laparoscopic pneumoperitoneum needle was used to perform suprappubic cystipuncture, and ureteral grasping forceps were inserted through the outer sheath. The forceps were used to fix the enencied gland. A rapid harvesting electric resection was performed in the broad space of the bladder, and the Ellick was rinsed to remove the tissue fragments. Surgical indicators and complications were recorded. The improvement of subjective score (IPSS, QOL, IIEF-5) and objective index (Q max, PVR) was compared between preoperative and postoperative. Results:All the 15 operations were completed successfully and there were no complications such as blood transfusion, capsule perforation, transurethral resection syndrome, bladder injury, bladder puncture site laceration and bleeding. The weight of resected prostate tissue was 44(40, 60)g, with blood loss (79.20±18.93)ml.The time of enucleation operation was (54.13±10.88)min, with harvest cutting time (14.67±2.50)min, evisceration efficiency (0.89±0.08)g/min, harvesting efficiency (3.26±0.36)g/min, bladder irrigation time (2.47±0.52) d. The time of indwelling catheter was (3.73±0.80)d.The postoperative hospital stay was (4.40±0.91) d. Temporary urinary incontinence occurred in 1 case after operation. All patients were followed up for 6 months after operation. The IPSS score was 3(2, 3), QOL score was 0(0, 1), IIEF-5 score was (20.12±2.30), Q maxwas (21.80±2.14) ml/s and PVR was 10(5, 15)ml, which were all significantly different compared with those before surgery ( P<0.05). The symptoms of the patients were significantly improved. Conclusions:Transurethral plasma enucleation of prostate combined with suprapubic bladder puncture and fixed gland is effective in the treatment of benign prostatic hyperplasia. The subjective symptoms and objective examination of patients have been significantly improved, and no adverse operation-related complications have occurred. It is a suitable method for enucleation of prostate in units which are not equipped with transurethral tissue planer.

Objective:To investigate the correlation between fluid-attenuated inversion recovery vascular hyperintensities(FVH) and prognosis and cognitive dysfunction in patients with internal watershed cerebral infarction(IWI).Methods:Totally106 patients with IWI were selected.According to FVH diagnostic criteria, there were 59 cases in FVH (+ ) group and 47 cases in FVH (-) group.Demographic data and risk factors of cerebrovascular disease were collected to assess the clinical neurological function of the patients at admission and discharge, and the short-term outcome was assessed by modified RANKIN scale (mRS) score at 90 days after discharge.The cognitive function of patients was assessed by MMSE scale.Results:There was no significant difference in NIHSS score between the two groups on admission ( P>0.05). The NIHSS score of FVH (+ ) group((3.37±2.33))at discharge was significantly lower than that of the FVH (-) group ((4.43±2.72))( P<0.05). The rate of neural function improvement and mRS score after discharge 90 days in FVH (+ ) group((42.16±12.20)%, (1.75±1.12)) was significantly higher than that in FVH (-) group((37.58±13.64)%, (2.19±1.38))(both P<0.05). The scores of orientation, recall and language ability of MMSE in FVH (+ ) group ((9.26±0.21), (1.66±0.27), (7.69±0.44) respectively)were significantly lower than those of FVH (-) group((9.43±0.36), (1.83±0.34), (7.85±0.28) respectively)(all P<0.05). There was no significant difference in memory, attention and calculation between the two groups ( P>0.05). Conclusion:FVH has no correlation with the severity of IWI patients when they are admitted to hospital.FVH may be used as an imaging sign for prognosis evaluation of patients with IWI .However, IWI patients with FVH may have more severe cognitive impairment.

Objective:To explore the clinical utility of liquid chromatography tandem mass spectrometry forprimary aldosteronism screening.Methods:From January to October 2019, 413 inpatients diagnosed hypertension from Fuwai Hospital of Chinese Academy of Medical Sciences were enrolled, including 60 Primary aldosteronism(PA)patients and 353 primary hypertension patients. The plasma aldosterone concentration (PAC) and renin concentration (DRC) were measured after 2 h of standing. The 24 h urine samples were collected for measurement of aldosterone using LC-MS/MS. The performance of urine aldosterone and urine aldosterone/renin ratio (UADRR) in PA screening was evaluated by ROC, and compared with PAC/DRC ratio (ADRR). Meanwhile, the efficiency of urine aldosterone in elderly patients or patients with low blood potassium or 24 h urine sodium over 200 mmol was investigated.Results:Area under the curve (AUC)of urine aldosterone was 0.725 (95 %CI 0.679-0.767), and the best cut-off was 7.13 μg/24 h, which was lower than AUC of ADRR (0.958, 95 %CI 0.934-0.975). The AUC of UADRR was 0.947 (95 %CI 0.920-0.966), the best cut-off was 1.11 (μg/24 h)/(μIU/ml), the sensitivity and specificity were 91.7% and 89.0%, respectively. There is no significant differences found with ADRR. In patients with 24 h urine sodium over 200 mmol, AUC of aldosterone was 0.834 (95 %CI 0.730-0.910) and the best cut-off was 9.31 μg/24 h. The sensitivity and specificity were 90.9% and 68.7%, respectively. For the elderly patients over 60 years old, the AUC of urinary aldosterone was 0.860 (95 %CI 0.770-0.925), and the best cut-off was 6.91 μg/24 h. The sensitivity and specificity were 84.6% and 81.3%, respectively. When admission blood potassium was less than 3.50 mmol/L, AUC of urinary aldosterone was 0.822 (95 %CI 0.684-0.917), and the best cut-off was 10.63 μg/24 h. The sensitivity and specificity were 85.7% and 66.7%, respectively. Conclusion:The detection of aldosterone in urine by LC-MS/MS can provide clinical information for PA screening, and the screening performance is better in patients with 24-hour urine sodium over 200 mmol, elderly patients or patients with low blood potassium. If combined with renin, screening efficiency was the same as that in ADRR.
